GameFileCacheService.startRescan (in MainPresenter.onResume)
does nothing if called before GameFileCacheService.startLoad.
Fixes a 3f71c36 regression where already added games would not
show up after app launch under specific circumstances.
Unfortunately the loading indicator still doesn't show up
during a rescan initiated by app launch, but that would
be more annoying to fix, so I will leave it for now.
When a save state is loaded, the IOS device serving bluetooth
is cast as BluetoothEmuDevice. If, however, a real Wiimote
with BT passthrough is used, this caused the game to crash.
Now the proper device class is used.
At a first glance it may look like a part of the code I added to
srawx in efeda3b has a bug when a == s. The code actually happens
to work correctly, but in the interest of making the code easier
to reason about, I'd like to change the way it's implemented. This
change should improve the pipelining a little in the a == s case too.
Fix Gamelist context menu item 'Open Containing Folder' opening wrong
target on Windows when game parent folder is [foobar] and grandparent
folder contains file [foobar].bat or [foobar].exe
Add trailing directory separator to parent folder path to force Windows
to interpret path as directory.

21c152f added a small hack to DVDInterface to keep WBFS and CISO
files working with Nintendo's "Error #001" anti-piracy check.
Unfortunately I don't think it's possible to support WBFS and
CISO without any kind of hack or heuristic, but what we can do
is replace the 21c152f hack (which applies regardless of file
format) with a hack that only is active when using WBFS or CISO.
This change is similar to 2a5a399, but the disc size is
calculated in a different way.
Add ! before unused variables to 'use' them.
Ubuntu-x64 emits warnings for unused variables because gcc decides
it should ignore the void cast around them. See thread for discussion:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66425
Loop index int i was being compared against GetControllerCount() which
returned a size_t. This was the only place GetControllerCount() was
called from so the change of return type doesn't disturb anything else.
Changing the loop index to size_t wouldn't work as well since it's
passed into GetController(), which takes an int and is called from many
places, so it would need a cast anyway on an already busy line.
...and let's optimize a divisor of 2 ever so slightly for good measure.
I wouldn't have bothered, but most GameCube games seem to hit this on
launch.

Add a function to calculate the magic constants required to optimize
signed 32-bit division.
Since this optimization is not exclusive to any particular architecture,
JitCommon seemed like a good place to put this.
Zero divided by any number is still zero. For whatever reason, this case
shows up frequently too.

Fairly common with constant dividend of zero. Non-zero values occur
frequently in Ocarina of Time Master Quest.
Whether the custom RTC setting is enabled shouldn't in itself
affect determinism (as long as the actual RTC value is properly
synced). Alters the logic added in 4b2906c.
I'm not entirely certain that this is correct, but the current
code doesn't really make sense to me... If we need to force the
RTC bias to 0 when custom RTC is enabled, why don't we need to
do it when custom RTC is disabled? The code for getting the
host system's current time doesn't contain any special handling
for the guest's RTC bias as far as I can tell.
The loop in WIARVZFileReader::Chunk::Read could terminate
prematurely if the size argument was smaller than the size
of an exception list which had only been partially loaded.
Fixes issue 11393.
The problem is that left and top make no sense for a width by height array; they only make sense in a larger array where from which a smaller part is extracted. Thus, the overall size of the array is provided to CopyRegion in addition to the sub-region. EncodeXFB already handles the extraction, so CopyRegion's only use there is to resize the image (and thus no sub-region is provided).
BPMEM_TEV_COLOR_ENV + 6 (0xC6) was missing due to a typo. BPMEM_BP_MASK (0xFE) does not lend itself well to documentation with the current FIFO analyzer implementation (since it requires remembering the values in BP memory) but still shouldn't be treated as unknown. BPMEM_TX_SETMODE0_4 and BPMEM_TX_SETMODE1_4 (0xA4-0xAB) were missing entirely.
Additional changes:
- For TevStageCombiner's ColorCombiner and AlphaCombiner, op/comparison and scale/compare_mode have been split as there are different meanings and enums if bias is set to compare. (Shift has also been renamed to scale)
- In TexMode0, min_filter has been split into min_mip and min_filter.
- In TexImage1, image_type is now cache_manually_managed.
- The unused bit in GenMode is now exposed.
- LPSize's lineaspect is now named adjust_for_aspect_ratio.
Additionally, VCacheEnhance has been added to UVAT_group1. According to YAGCD, this field is always 1.
TVtxDesc also now has separate low and high fields whose hex values correspond with the proper registers, instead of having one 33-bit value. This change was made in a way that should be backwards-compatible.
We want to save the currently selected platform tab,
but doing so immediately after switching tabs leads to
unnecessarily much file I/O (on the main thread, no less).
This change makes us defer the saving until later.
In master, the game scanning process looks like this:
1. Scan for games
2. Scan for additional metadata (icon.png and meta.xml)
3. Save the cache if needed
4. Update the game list with the results
This change makes the game scanning process look like this:
1. Scan for games
2. Update the game list with the results
3. Scan for additional metadata (icon.png and meta.xml)
4. Update the game list with the results
5. Save the cache if needed
Updating the game list as soon as possible means the user
has to wait less before their games show up. The new behavior
matches what DolphinWX did before it was removed. (DolphinQt
has an even fancier approach where games get added one by one.)
The PPC is supposed to be held in reset when another version of IOS is
in the process of being launched for a PPC title launch.
Probably doesn't matter in practice, though the inaccuracy was
definitely observable from the PPC.
We should only try to load a symbol map for the new title *after* it
has been loaded into memory, not before. Likewise for applying HLE
patches and loading new custom textures.
In practice, loading/repatching too early was only a problem for
titles that are launched via ES_Launch. This commit fixes that.
The extra IPC ack is triggered by a syscall that is invoked in ES's
main function; the syscall literally just sets Y2, IX1 and IX2 in
HW_IPC_ARMCTRL -- there is no complicated ack queue or anything.
Low MEM1 is cleared by IOS before all the other constants are written.
This will overwrite the Gecko code handler but it should be fine
because HLE::Reload (which will set up the code handler hook again)
will be called after a title change is detected.
The Host constructor sets a callback on a lambda that in turn calls
Host_UpdateDisasmDialog. Since that function is not a member function
capturing this is unnecessary.
Fixes -Wunused-lambda-capture warning on freebsd-x64.
When reading a reply from a message sent to the data socket there is
the possibility that the other side gets sent multiple messages
before replying to any of them, which can lead to multiple replies
sent in a row. Though this only happens when things time out, it's
quite possible for these timeouts to happen or build up over time,
especially when initiating the connection.
This change makes sure to flush any pending bytes that have not been
read yet out of the socket after a successful POLL reply is received,
since that is the most common time when backups occur, and as well as
using the exact number of bytes in an expected reply, to ensure
the received data and the message it's replying to do not get out of
sync.
The result of calls to PPCSTATE_OFF_PS0/1 were being cast to u32 and
passed to functions expecting s32 parameters. This changes the casts
to s32 instead.
One location was missing a cast and generated a warning with VS which
is now fixed.
Added `ToggleBreakPoint` to both interface BreakPoints/MemChecks. this would allow us to toggle the state of the breakpoint.
Also the TMemCheck::is_ranged is not longer serialized to string, since can be deduce by comparing the TMemCheck::start_address and TMemCheck::end_address
DualShock UDP Client is the only place in the code that assumed OnConfigChanged()
is called at least once on startup or it won't load up the setting, so I took care of that
The main reason why I'm adding this isn't actually to allow
users to swipe down to refresh, it's to add a loading indicator.
Considering that the Storage Access Framework can be slow for
folders with many items (many subfolders?), not showing a
loading indicator might give users the impression that adding
a folder resulted in nothing happening even though Dolphin is
scanning for games in the background. But I suppose letting
users swipe down to refresh is a nice bonus with the change.
This was caused, because we were saving the `break_on_hit` flag with the letter `p`. Then while loading the breakpoints, we read the flag with the letter `b`, resulting in the `break_on_hit` flag being always false
Filesystem accesses aren't magically faster when they are done by ES,
so this commit changes our content wrapper IPC commands to take FS
access times and read operations into account.
This should make content read timings a lot more accurate and closer
to console. Note that the accuracy of the timings are limited to the
accuracy of the emulated FS timings, and currently performance
differences between IOS9-IOS28 and newer IOS versions are not emulated.
Part 1 of fixing https://bugs.dolphin-emu.org/issues/11346
(part 2 will involve emulating those differences)
This makes it more convenient to emulate timings for IPC commands that
perform internal IOS <-> IOS IPC, for example ES relying on FS
for filesystem access.
According to hwtests, older versions of IOS are slower at performing
various filesystem operations:
https://docs.google.com/spreadsheets/d/1OKo9IUuKCrniz4m0kYIaMP_qFtOCmAzHZ_zAmobvBcc/edit
(courtesy of JMC)
A quick glance at IOS9 reveals that older versions of IOS have a
simplistic implementation of memcpy that does not optimize large copies
by copying 16 bytes or 32 bytes per chunk, which makes cached reads
and writes noticeably slower -- the difference was significant enough
that the OoT speedrunning community noticed that IOS9 (the IOS that
is used for the OoT VC title) was slower.
More or less a complete rewrite of the function which aims
to be equally good or better for each given input, without
relying on special cases like the old implementation did.
In particular, we now have more extensive support for
MOVN, as mentioned in a TODO comment.
Instead of constructing IPCCommandResult with static member functions
in the Device class, we can just add the relevant constructors to the
reply struct itself. Makes more sense than putting it in Device
when the struct is used in the kernel code and doesn't use any Device
specific members...
This commit also changes the IPC command handlers to return an optional
IPCCommandResult rather than an IPCCommandResult. This removes the need
for a separate boolean that indicates whether the "result" is actually
a reply, and also avoids the need to set dummy result values and ticks.
It also makes it really obvious which commands can result in no reply
being generated.
Finally, this commit renames IPCCommandResult to IPCReply since the
struct is now only used for actual replies. This new name is less
verbose in my opinion.
The diff is quite large since this touches every command handler, but
the only functional change is that I fixed EnqueueIPCReply to
take a s64 for cycles_in_future to match IPCReply.
PrepareForState is now unnecessary with the new implementation of
HostFileSystem::DoState, which does what the old implementation
(CWII_IPC_HLE_Device_FileIO::PrepareForState) used to do.
I don't really see the use of this. (Maybe in the past it
was used for when we need a constant number of instructions
for backpatching? But we don't use MOVI2R for that now.)
Now that the ES class (now called ESDevice) and the ES namespace do
not conflict anymore, "IOS::" can be dropped in a lot of cases.
This also removes "IOS::HLE::" for code that is already in that
namespace. Some of those names used to be explicitly qualified
only for historical reasons.
There are no functional changes.
Some of the device names can be ambiguous and require fully or partly
qualifying the name (e.g. IOS::HLE::FS::) in a somewhat verbose way.
Additionally, insufficiently qualified names are prone to breaking.
Consider the example of IOS::HLE::FS:: (namespace) and
IOS::HLE::Device::FS (class). If we use FS::Foo in a file that doesn't
know about the class, everything will work fine. However, as soon as
Device::FS is declared via a header include or even just forward
declared, that code will cease to compile because FS:: now resolves
to Device::FS if FS::Foo was used in the Device namespace.
It also leads to having to write IOS::ES:: to access ES types and
utilities even for code that is already under the IOS namespace.
The fix for this is simple: rename the device classes and give them
a "device" suffix in their names if the existing ones may be ambiguous.
This makes it clear whether we're referring to the device class or to
something else.
This is not any longer to type, considering it lets us get rid of the
Device namespace, which is now wholly unnecessary.
There are no functional changes in this commit.
A future commit will fix unnecessarily qualified names.
According to the C standard, an offsetof expression must evaluate to an
address constant, otherwise it's undefined behavior.

There are still improper uses of offsetof (mostly in JitArm64) but
fixing that will take more effort since there's a PPCSTATE_OFF wrapper
macro that is sometimes used with non-array members and sometimes used
with arrays and variable indices... Let's keep that for another PR.
